CVE-2018-19960

Name of the Vulnerable Software and Affected Versions OnionShare versions 1.3.1 and earlier

Description The issue concerns the debug mode function in web/web.py, which uses the /tmp/onionshare server.log pathname for logging when --debug is enabled. This might allow local users to overwrite files or obtain sensitive information by using this pathname.

Recommendations For OnionShare versions 1.3.1 and earlier, as a temporary workaround, consider disabling the debug mode function until a patch is available. Restrict access to the /tmp/onionshare server.log file to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
